REGULATORY STATUS

moderately toxic

INTRODUCTION

causing injury only to the parts of the plant to which it is applied
it does not spare 'nontarget' plants from its herbicidal effects
causes a leaf or an entire plant to dry out quickly

ACUTE TOXICITY

moderately toxic
fatal to humans if swallowed, inhaled, or absorbed through the skin
Concentrated solutions may cause severe irritation of the mouth, throat, esophagus and stomach followed by nausea, vomiting, diarrhea, severe drying out of bodily tissues, gastrointestinal discomfort, chest pain, diarrhea, kidney failure, and toxic liver damage
Very large doses of the herbicide can result in convulsions and tremors
Rats given lethal doses of diquat showed few signs of illness during the first 24 hours. They then exhibited lethargy, pupil dilation, respiratory distress, weight loss weakness and finally death over the course of 2 to 14 days after dosing. Similar patterns of symptoms occurred in mice, guinea pigs, rabbits, dogs, cows and hens
acutely toxic when it is absorbed through the skin and the possibility for poisoning increases with repeated exposure
demonstrated toxicity of this compound is sufficient to raise serious human health concerns. Small amounts of diquat can cause skin irritation and sores, as well as delayed healing of cuts and wounds. When absorbed through the skin, some commercial concentrate formulations of diquat can cause symptoms similar to those that occur when it is eaten
There have been reports of workers who have had softening and color changes in one or more fingernails after contact with concentrated diquat dibromide solutions. In some instances, the nail was shed, and did not grow in again
Repeated dermal doses cause mild redness, thickening, and scabbing
Diquat dibromide also causes eye irritation
Several cases of severe injury to human eyes have been reported after accidental splashings. In each case, initial irritation was mild, but after several days, serious burns and sometimes scarring of the cornea developed
Direct or excessive inhalation of diquat dibromide spray mist or dust may result in oral or nasal irritation, nosebleeds, headache, sore throat, coughing, and symptoms similar to those from ingestion of diquat

CHRONIC TOXICITY

Cataract formation is the most significant effect of chronic exposure to diquat
repeated, or prolonged, dermal contact with diquat dibromide range from inflammation of the skin, to general bodily ('systemic') poisoning, as evidenced by injury to internal organs, primarily the kidneys.
Chronic exposure may damage skin, which allows more absorption of the herbicide
Repeated applications of 42 mg/kg of diquat killed four out of six rabbits tested
Repeated inhalation exposure of rats to 1.9 mg/m3 caused inflammatory changes in connective tissues, damage to the kidneys and heart, abnormal levels of several liver enzymes, low white blood cell counts, high red blood cell counts, and depressed cholinesterase activity

Reproductive Effects

Fertility was reduced in male mice given diquat dibromide during different stages of sperm formation

Teratogenic Effects

diquat dibromide is thought by other researchers to have the potential to cause birth defects

Organ Toxicity

diquat is most harmful to the gastrointestinal tract (GIT), kidneys, and liver
Severe congestion and ulceration of the stomach and bowel are produced by the herbicide
large doses of diquat are given, there is evidence of stretching and irritation of the GIT and thickening of the walls of the alveoli, or air cells of the lungs
Acute death occurs in the cells of the small glandular tubes that process urine in the kidney
Cataracts are caused when smaller amounts of diquat are given
water is apparently removed from other tissues as well
Dehydration can result
amount of water which is removed depends on how much diquat dibromide is given
Poisoning by diquat may affect the liver and kidneys

Fate in Humans and Animals

Diquat dibromide may be absorbed by humans following oral ingestion, dermal exposure or inhalation of spray mists
Oral doses of diquat are metabolized mainly within the intestines rather than in the body proper, with metabolites being excreted in the feces
cattle an oral dose was recovered in the milk

Effects on Birds

moderately toxic to practically nontoxic to birds
Signs of poisoning... included instability, wing-drop and lack of movement

Effects on Aquatic Organisms

Diquat dibromide is slightly toxic to fish
lethal concentration fifty, or LC50 is that concentration of a chemical in air or water that kills half of the experimental subjects exposed
Some species of fish may be harmed
Oxygen can become depleted in diquat-treated water by decaying aquatic plants. This decreases the amount of oxygen available for fish survival.
yellow perch suffer significant respiratory stress
Strip application of the herbicide over water is recommended to prevent large scale fish kills
One investigation into the persistence of diquat in fish showed that one half of the herbicide was lost in less than three weeks

Effects on Other Animals (Nontarget species)
Cows are particularly sensitive to the toxic effects of this material

Breakdown of Chemical in Soil and Groundwater

diquat dibromide comes in contact with soil, it becomes strongly adsorbed to clay particles or organic matter in the soil for long periods of time
strong chemical bonds formed by diquat adsorption to soil particles make the herbicide biologically and chemically inactive.
- carried away, or leached, by water seeping through the soil
Traces, or residues, of diquat have been found to persist in soil for many years with very little degradation
Soil capacity for adsorption of diquat is so high...
there is also evidence that diquat has the ability to eventually use up, or saturate, all the available adsorption sites on soil clay particles
Groundwater quality can be affected if soil adsorption sites become totally saturated because water moving down through the soil can carry any non adsorbed herbicide into the groundwater
Studies on the erosion of diquat-treated soils near bodies of water indicate that diquat stays bonded to soil particles, remaining biologically inactive in surface waters, such as lakes, rivers and ponds

Breakdown of Chemical in Water

diquat is applied to open water, it disappears rapidly because it binds to suspended particles in the water. These particles are then taken up by plants
Twenty-two days after a weed infested artificial lake was treated, only 1% of the applied diquat remained in the water and 19% was adsorbed to sediments.
Diquat has been found in the bottom soil of pools and ponds four years after application
Diquat will photodegrade in surface layers of water in 1 to 3 or more weeks when it is not adsorbed to suspended particles
The EPA requires a 14-day interval between treatment of water with diquat dibromide and use of treated waters for domestic, livestock, or irrigation purposes. Swimming, fishing and watering of domestic animals should not be allowed for at least 14 days after application of the herbicide to water. The herbicide cannot be used for any purpose in commercial fish processing areas

Breakdown of Chemical in Vegetation

intermediate residues of diquat are incorporated with the plant materials into the soil, where, through a process called 'microbial degradation, they are changed into carbon dioxide by soil microorganisms
Diquat dibromide is also rapidly absorbed by weeds in water, which causes the concentrations of the material in plant tissue to be higher than in surrounding water.
Low concentrations of the herbicide in water are adequate for controlling aquatic weeds
diquat dibromide is a nonselective herbicide with non-crop use patterns that overlap endangered plant habitats, it may present a danger to nontarget plants, including endangered species

PHYSICAL PROPERTIES AND GUIDELINES

contains small amounts of a highly toxic chemical impurity, ethylene dibromide (EDB)
When heated to decomposition, very toxic fumes are emitted from diquat
pose a slight fire hazard if exposed to heat or flame
poses a fire and explosion hazard in the presence of strong oxidizers
Thermal decomposition of diquat will release toxic oxides of nitrogen and carbon and toxic and corrosive fumes of bromides
Diquat is corrosive
Commercial use formulations of diquat contain corrosion inhibitors, ingredients that slow down or prevent corrosion
corrosion inhibitors, concentrated formulations will corrode metals, especially aluminum, and should be stored only in the original container
diquat dibromide is incompatible with anionic wetting agents such as alkyl sulfamates
protective clothing should be worn when handling the concentrated product
Skin and eye contact with diquat, especially from drift, should be avoided
Breathing diquat spray (mist) should also be avoided
Respiratory equipment is recommended, especially in situations in which exposure to drifting spray is possible
24-hour reentry interval is set by EPA for crop sites, golf courses, and rights-of-way that are treated with diquat dibromide
14-day period is also required by EPA between diquat treatment of water bodies and use of treated water for domestic, swimming, irrigation, and/or livestock feeding purposes
Diquat dibromide may not be used where commercial fish processing is practiced
